and State of New York, have-invented cer' tain new and usefulImprovements in Gement Facing-Slabs, of WhlCll the following isaspecification. i

This invention relates to an im roved ce-' ment facing-slab forbuildings w ch is intended to be used in lace of stonebuilding blocks orslabs for private dwellings, apartmer t-houses, and larger buildings,said slab ha'vmg the advantage of being made up for 'dlrect connectionw1th the wooden or iron framework of the building; and for this purosethe invention consists of a cement facmg-slab which is provided withlongitudinal sta -rods which are bent up at'their ends an provided witheyes or loops at their outerends and with 11 right transverse rods thatare embedded, like the longitudinal stay-nods', in the bod of the slaband serve for retaining the lbn itudinal stay-rods firmly in position inthe s ab.

Inthe accompanying drawings a Figure 1 represents a persp'ectiverearview of my improved cement facin -block; and Figs. 2 and 3 arerespectively a horizontal section and a vertical transverse section onlines 2 2 and 3 3, Fi :1.

Simi ar letters of reference indicate corresiponding parts in thedifferent figures of the awings.

Referrin to the drawings, a represents a cement sla b or block of anydesired size which is formed in a suitable mold and made of a goodquality of cement mixed in suit-, able proportions with a ood. qualityof sand. A layer of the sand and cement mixture of suitable thickness isplaced into the mold. and tamped so as to uniforml fill up the courseand bottom of the mold -Two longitudinal stay-rods b are then placedinto the tamped layer of cement, and near the longer ends of the same ashorter stay-rod b is placed, both the longer and shorter stay-rods emgbent up at the ends and rovided with eyes'or loops 1). The longitu inalportions of the stay-rods b are pressed into the cement and retained inthe same by means of transverse rods d, which are placed across thestay-rods near the ends and middle portion of the same, as 'shownclearlyin Figs. 1 and 2. After the longitudinal and transverse staypleted bytamping a sufficient quantity of the so as to form the -requiredthickness of. the block and bring the stay-rods as nearly as possibleinto the center of the block. The ent-up portions of the longitudinalstay-rods are made ofsuch length as toextendto the outside of the block,so as to ermit the convenient attaching of the bloc as the same areplaced in POSI'DTOII on the building to the wooden or iron framework ofthe same. Connection is made by means of wires of suitable strengthwhich are passed through the loops or eyes 12 and which are wound.around the upright studs ofthe buildin The blocks are permitted to sitin the mol s and dry. Then they are removed from the before being used.I a

The molds are. preferably made of smoothfaced cast-iron, so that theface, sides, and ends are in perfectly smooth condition 1n order thatthe blocks can be used directly without requiring further 'finishing.xThe ered with tar or other as halt composition so as to render theslabs or looks waterproof. The slabs or blocks are joined by a suitablemortar and may be painted on the outside tect the blocks fluences.

facing-slabs for uildings are, first, that they size in a suitablefactory and after? being properly dried shipped to the place -ofuse;second,=that they dispense with naturale by Letters molds andpermittedtd harden sufficiently rear surfaces of the slabs or blocks arecovcan be made up in the required number and grown stone slabs and thehandecutting of the thus described my .invention,*I-

rods are placed position the block is coma cement and sand compositioninto the mold,

l with some waterproof coating so as to pro.- against atmosphenc 1n- Theadvanta es of my improved cement rods extending over the long itudina'lstayrods, both being embedded 1n the body of the slab.

2. A facing slab or block for building purposes, consisting of a cementbody of suitable size provided with longitudinal stay-rods near thelongitudinal sides and an intermediate shorter stay-rod, 'saidlongitudinal stayrods being bent up at their ends and rovided With eyesor loops at the outside of t e block, and transverse stay-rods extendingover the longitudinal stayrods,- both the longitudinal and transverses'ta -rods bein located ap'-- Eroximately near t e center 0 the slab andeing embedded in the body of the same, While the eyes or loops projectfrom the rear of the same.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses;
